Sum Master

Sum Master is a brain-boosting number puzzle game that challenges your logic, sharpens your mental math, and keeps you hooked with its deceptively simple rules, deep strategic play, and fun gameplay. Perfect for browser and mobile players alike, this Sudoku-style game offers a refreshing twist on classic number puzzles.

Your goal? Select the right numbers from a grid so that each row, column, and colored region adds up to its target sum. It sounds simple, but with each level featuring a unique solution, your logic and arithmetic skills will be put to the ultimate test. Think carefully, because one wrong number could throw your whole grid off balance.

With six difficulty levels ranging from Easy (4x4 grids) to the mind-melting Extreme (9x9), Sum Master scales with your skill — whether you're looking for a casual challenge or a serious brain workout. But be careful: you only get three hearts, and each wrong selection costs one.

Clean, minimalist visuals paired with a satisfying, clue-based system make Sum Master ideal for fans of Sudoku, Kakuro, and other logic games. Can you master the sums and conquer the grid? Play anywhere, anytime — and prove your mind is sharper than the sum of its parts.
